Description

Technical Field

[0001] The utility model relates to the field of monazite processing, in particular to a monazite slurry rapid pumping device. Background Art

[0002] The name of monazite comes from the fact that it often exists as a single crystal. It is a phosphate mineral containing cerium and lanthanum, and a rare earth mineral, often containing thorium, zirconium, etc. It is a monoclinic system, and the crystals are small and plate-shaped. Monazite can be used to extract rare earths. Monazite is ground into a slag and water and other solvents are added to form a slurry. Other solvents are added to the monazite slurry to extract rare earths. There are many ways to process the slurry, including using the supernatant to filter and squeeze it for extraction, and adding solvents to react for extraction. However, in the existing system, the slurry pump cannot adapt to a variety of working methods, and the solvent is not mixed very evenly when it is mixed into the slurry.

[0003] Therefore, in order to solve the above problems, a monazite slurry rapid pumping device is specifically proposed. Utility Model Content

[0004] The utility model aims at solving the above-mentioned problems and specifically designs a monazite slurry rapid pumping device, which can pump the slurry in the slurry storage tank and pump the slurry to other processes for processing, or perform circulating pumping work, adding a reaction solvent to react with the slurry during the circulation, so as to achieve a better mixing effect of the solvent.

[0005] To achieve the above-mentioned purpose, the utility model provides a monazite slurry rapid pumping device, comprising: a pumping system, a slurry storage tank and a dosing device, the pumping system comprises: a suction pipe, a return pipe and a slurry pump, the suction pipe and the return pipe are respectively connected to the suction end and the output end of the slurry pump, the other end of the suction pipe is connected to the bottom of the slurry storage tank, the other end of the return pipe is placed above the slurry storage tank, and the dosing device is connected to the return pipe.

[0006] In the above manner, the slurry pump sucks the slurry out of the slurry storage tank and transports the slurry back to the slurry pump through the reflux pipe. The solvent can be added to the reflux pipe through the dosing device. The slurry passing through the dosing device will contact the solvent, thereby improving the fusion effect of the solvent and the slurry.

[0007] Furthermore, the dosing device includes a dosing bin and a feeding port, the dosing bin is a cylindrical tube structure, the dosing bin is connected to the reflux pipe and the internal space is communicated with the reflux pipe, and a plurality of the feeding ports are opened on the dosing bin.

[0008] Furthermore, it also includes a supernatant suction pipe and a delivery pipe, and the pumping system also includes a three-way interface, one end of the supernatant suction pipe is connected to the suction pipe through the three-way interface, the other end of the supernatant suction pipe is connected to the upper part of the slurry storage tank, one end of the delivery pipe is connected to the reflux pipe through the three-way interface, and the other end of the delivery pipe is connected to the filter press.

[0009] Through the above method, after the slurry in the slurry storage tank is precipitated, the supernatant liquid on the top can be used for the remaining processes. The slurry pump extracts the supernatant liquid through the supernatant liquid suction pipe and transports the supernatant liquid to the next process through the delivery pipe.

[0010] Furthermore, it also includes a mixing device, which is installed on the return pipe and is located behind the dosing device in the slurry flow direction.

[0011] Furthermore, the mixing device is of a cylindrical structure, both ends of the mixing device are connected to the reflux pipe, a stirring device is vertically installed inside the mixing device, and the stirring device is horizontally installed inside the dosing device.

[0012] Furthermore, the stirring device includes a stirring blade and a positioning bracket, one end of the positioning bracket is fixedly connected to the inner wall of the pipe, the other end of the positioning bracket is placed on the axis of the pipe and fixedly connected to a rotating shaft, and the stirring blade is rotatably connected to the rotating shaft on the positioning bracket.

[0013] Furthermore, it also includes a bracket, which is placed between the slurry pump and the slurry storage tank. A binding belt is hung on the bracket, and the binding belt is connected to the return pipe.

[0014] In the above manner, a stirring device is installed inside the mixing device, which can stir the slurry passing through to improve the mixing effect of the solvent and the slurry. The stirring device in the dosing device can disperse the solvent that has just entered. The principle of the stirring device is that when the slurry passes through, the slurry impacts the stirring blade. The blade of the stirring blade is inclined, and the height of one side is lower than the other side. Therefore, under the impact of the fluid, the blade will deflect, so the stirring blade rotates around the rotating shaft.

[0015] In summary, the monazite slurry rapid pumping device of the utility model has the following advantages and beneficial technical effects:

[0016] 1. The utility model provides a monazite slurry rapid pumping device that can adapt to the different process requirements of monazite, and can be applied to the method of stealing and dissolving, and can also be applied to the method of using the supernatant for reprocessing, saving the funds and space requirements for installing redundant equipment for different processes;

[0017] 2. The dosing device in the monazite slurry rapid pumping device of the utility model can add solvent to the slurry when it flows, thereby improving the mixing effect of the slurry and the solvent, and further improving the extraction efficiency of rare earth;

[0018] 3. The stirring device of the monazite slurry rapid pumping device of the utility model can utilize the flow of liquid to rotate, and at the same time, it has a simple structure and utilizes the flow of slurry to achieve a stirring effect. BRIEF DESCRIPTION OF THE DRAWINGS
